Deactivation of Ni spinel derived catalyst during the oxidative steam reforming of raw bio-oil
Arandia Gutiérrez, Aitor; Remiro Eguskiza, Aingeru; Oar Arteta, Lide; Bilbao Elorriaga, Javier; Gayubo Cazorla, Ana Guadalupe (Elsevier, 2020-05-12)Deactivation of a bulk catalyst derived from NiAl2O4 spinel during the oxidative steam reforming (OSR) of raw bio-oil has been studied. The experiments were performed in a continuous system with two units in series: a ... -
Hydrogen production by steam reforming of bio-oil/bio-ethanol mixtures in a continuous thermal-catalytic process
Remiro Eguskiza, Aingeru; Valle Pascual, Beatriz; Oar Arteta, Lide; Aguayo Urquijo, Andrés Tomás ; Bilbao Elorriaga, Javier; Gayubo Cazorla, Ana Guadalupe (Elsevier, 2014-04-24)The feasibility of the steam reforming of bio-oil aqueous fraction and bio-ethanol mixtures has been studied in a continuous process with two in-line steps: thermal step at 300 ºC (for the controlled deposition of pyrolytic ... -
Origin and nature of coke in ethanol steam reforming and its role in deactivation of Ni/La2O3-αAl2O3 catalyst
Montero, Carolina; Remiro Eguskiza, Aingeru; Valle Pascual, Beatriz; Oar Arteta, Lide; Bilbao Elorriaga, Javier; Gayubo Cazorla, Ana Guadalupe (ACS, 2019-07-22)Deactivation of Ni/La2O3-αAl2O3 catalyst in the ethanol steam reforming (ESR) was studied in order to establish the optimal conditions for maximizing H2 production and achieving a steady behaviour. The ESR reactions were ... -
Reaction conditions effect and pathways in the oxidative steam reforming of raw bio-oil on a Rh/CeO2-ZrO2 catalyst in a fluidized bed reactor
Arandia Gutiérrez, Aitor; Remiro Eguskiza, Aingeru; Oar Arteta, Lide; Bilbao Elorriaga, Javier; Gayubo Cazorla, Ana Guadalupe (Elsevier, 2017-12-07)A reaction scheme has been proposed for the oxidative steam reforming (OSR) of raw bio-oil on a Rh/CeO2-ZrO2 catalyst, based on the study of the effect reaction conditions (temperature, space time, oxygen/carbon ratio and ... -
Regeneration of NiAl2O4 spinel type catalysts used in the reforming of raw bio-oil
Remiro Eguskiza, Aingeru; Arandia Gutiérrez, Aitor; Oar Arteta, Lide; Bilbao Elorriaga, Javier; Gayubo Cazorla, Ana Guadalupe (Elsevier, 2018-12-01)The regenerability of Ni catalysts in reforming reactions is a key factor for process viability. Accordingly, this study addresses the regeneration of two spinel NiAl2O4 type catalysts by reaction-regeneration cycles in ... -

Remiro Eguskiza, Aingeru; Arandia Gutiérrez, Aitor; Oar Arteta, Lide; Bilbao Elorriaga, Javier; Gayubo Cazorla, Ana (ACS, 2018-02-21)The oxidative steam reforming (OSR) of raw bio-oil (obtained by fast pyrolysis of pine sawdust) has been studied on a Rh/CeO2-ZrO2 catalyst under a wide range of operating conditions (600-750 ºC; steam to carbon molar ratio ... -
Stability of CuZnOAl2O3/HZSM-5 and CuFe2O4/HZSM-5 catalysts in dimethyl ether steam reforming operating in reaction-regeneration cycles
Oar Arteta, Lide; Remiro Eguskiza, Aingeru; Vicente, Jorge; Aguayo Urquijo, Andrés Tomás ; Bilbao Elorriaga, Javier; Gayubo Cazorla, Ana Guadalupe (Elsevier, 2014-05-21)The study focuses on the regenerability of bifunctional catalysts prepared with different metallic functions (CuZnOAl2O3 and CuFe2O4 spinel) and HZSM-5 zeolite (SiO2/Al2O3 = 30) as the acid function. These catalysts have ...
